Description

Electronic device TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of lighting devices, and in particular to an electronic device. BACKGROUND

[0002] Many products are currently designed with light-emitting devices, which can serve as indicators and enhance the aesthetic appearance. However, it is difficult to design complex lighting for products with small spaces. Moreover, the light source contains metal, which may interfere with the function of other modules (such as antennas) in the product. Therefore, the light source needs to be at a sufficient distance from other affected modules. This requires the volume of the light source to be as small as possible and concentrated, and the device volume to be reduced as much as possible without affecting other modules.

[0003] Therefore, it is necessary to provide an electronic device to realize the miniaturization and integration of the light source. SUMMARY

[0004] The present disclosure provides an electronic device that can reduce the volume of the light source and improve the concentration of the light source.

[0005] The present disclosure provides an electronic device, which includes a housing and a light-emitting assembly mounted on the housing, the light-emitting assembly including a light source configured to emit light outwardly and a light guide including an incident surface facing the center of the housing and an exit surface opposite to the incident surface, the exit surface being exposed outside the housing.

[0006] In some embodiments, the light-emitting assembly further includes a reflective member disposed on one side of the light guide and shielding at least part of the surface of the light guide outside the incident surface and the exit surface.

[0007] In some embodiments, the at least part of the surface includes a surface of the light guide opposite to the exit surface.

[0008] In some embodiments, the reflective member includes a top wall and a side wall, the top wall being disposed opposite to the surface of the light guide opposite to the exit surface, and the side wall being connected to the top wall and distributed around the light guide.

[0009] In some embodiments, the surface of the light guide opposite to the exit surface is provided with a plurality of light-exit light guide points.

[0010] In some embodiments, one of the plurality of light-exit light guide points includes a groove.

[0011] In some embodiments, a surface of the light guide opposite to the light exit surface is inclined relative to the light exit surface, and a distance from the light exit surface at one end of the surface of the light guide away from the light entrance surface is shorter than a distance from the light exit surface at one end of the surface of the light guide close to the light entrance surface.

[0012] In some embodiments, the light entrance surface is provided with a plurality of light entrance light guide points.

[0013] In some embodiments, one of the plurality of light entrance light guide points comprises a protrusion.

[0014] In some embodiments, the protrusion comprises a plurality of intersecting surfaces.

[0015] In some embodiments, the housing comprises a mounting hole through which the light exit surface is exposed outside the housing, and a contour of the mounting hole matches a contour of the light exit surface.

[0016] In some embodiments, when the number of the light guides is a plurality, the light guides within a preset first threshold distance are connected by a connecting piece, and a light transmittance of the connecting piece is lower than a preset second threshold.

[0017] In some embodiments, the connecting piece and the connected light guides are integrally formed by means of two-shot injection molding.

[0018] In summary, in the electronic device provided by the embodiments of the present disclosure, the light entrance surface and the light exit surface of the light guide are arranged as non-parallel surfaces. The light entrance surface is arranged at one end of the light exit surface close to the center of the housing and faces the center of the housing. Therefore, the light entrance surface is closer to the center of the housing relative to the light exit surface. The light source is opposite to the light entrance surface. Therefore, the light source can be closer to the center of the housing. No matter where the light exit surface is located and in which direction, the light source can be concentrated in the direction close to the center of the housing, so that the light source is located in the area of the center of the housing, the volume of the light source is reduced, and the concentration of the light source is improved. At the same time, since the light entrance surface faces the center of the housing, no matter where the light exit surface is located and in which direction, the light source only needs to be opposite to the light entrance surface, so that the arrangement of the light source is simpler.

[0030] The following description provides specific applications and requirements of the present disclosure, which is intended to enable those skilled in the art to make and use the contents of the present disclosure. Various local modifications of the disclosed embodiments are apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure is not limited to the embodiments shown, but is consistent with the widest scope of the claims.

[0031] The terms used herein are only for the purpose of describing specific example embodiments, and are not limiting. For example, unless the context clearly indicates otherwise, as used herein, the singular forms "a", "an", and "the" can also include the plural forms. When used in the present disclosure, the terms "comprise", "include" and / or "contain" mean that the associated integers, steps, operations, elements and / or components exist, but do not exclude the presence of one or more other features, integers, steps, operations, elements, components and / or groups. When used in the present disclosure, the term "A on B" can mean that A is directly adjacent to B (above or below), or can mean that A is indirectly adjacent to B (i.e. there is some material between A and B); the term "A in B" can mean that A is entirely inside B, or can mean that A is partially inside B.

[0032] These and other features, and characteristics of the present disclosure, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the present disclosure.

[0033] These and other features, and characteristics of the present disclosure, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the present disclosure.

[0034] At present, many products are designed with light-emitting devices, which can play an indicating role on one hand and have the effect of enhancing the appearance on the other hand. For many products with small space, it is difficult to design complex light. Especially for communication devices, since an antenna is arranged in the communication device, in order to ensure the stability of the antenna, a sufficient clearance area needs to be left for the antenna. No metal-containing parts can be arranged in the clearance area of the antenna. The light source contains metal. Therefore, the light source needs to be at a sufficient distance from the antenna module. This requires the volume of the light source to be as small as possible and concentrated, and the device volume is reduced as much as possible without affecting other modules.

[0035] The electronic device provided by the embodiments of the present disclosure uses a side light-emitting light guide scheme, and the light source is arranged on the side of the light guide piece. The light-in surface of the light guide piece is not parallel to the light-out surface, and the light-in surface is arranged at one end of the light-out surface close to the center of the shell and faces the center of the shell, so that the light-in surface is closer to the center of the shell than the light-out surface. Since the light source is opposite to the light-in surface, the light source emits light on the side of the light-out surface of the light guide piece, and the light is incident into the light-in surface from the side of the light-out surface. In the side light-emitting light guide scheme, the light source can be closer to the center of the shell. Such an arrangement allows the light source to be concentrated in the direction close to the center of the shell regardless of the position and direction of the light-out surface, so that the light source is located in the region of the center of the shell, thereby reducing the volume of the light source and improving the concentration of the light source. At the same time, since the light-in surface faces the center of the shell, in the complex light design, the light source only needs to be opposite to the light-in surface regardless of the direction and position of the light-out surface, so that the light source arrangement is simpler.

[0036] The electronic device provided by the present disclosure can be any form of electronic device and can be applied to any scenario. The electronic device includes, but is not limited to, a payment device, a wearable device, a smart home appliance, and the like. The electronic device can be installed with a communication module. The communication module can be used to communicate with other electronic devices to interact information. The communication module can transmit and / or receive radio frequency signals. The communication module is provided with a communication antenna, and the radio frequency signals are transmitted and / or received through the communication antenna. The communication module can be any one or more of a wireless communication module, such as a WiFi module, a Bluetooth module, and an NFC (Near Field Communication) module. The communication module can be an active communication module working in an active mode or a passive communication module working in a passive mode, or a combination of the active communication module and the passive communication module. The active mode can be that the active communication module actively transmits radio frequency signals to identify and read other passive communication devices working in the passive mode. The passive mode can be that the passive communication module receives or senses other active communication devices working in the active mode within a sensing area (usually an antenna coverage area) to communicate with the active communication device. Among them, the near field communication technology is widely used due to its short communication distance, fast transmission rate, and high security. In some embodiments, the communication module in the electronic device provided by the present disclosure is a near field communication module. The electronic device provided by the present disclosure can be applied to scenarios such as payment through the communication module, ordering through the communication module, information transmission through the communication module, device connection through the communication module, and the like.

[0037] Taking the electronic device as a payment device as an example. FIGS. 1A-1C show application scenario diagrams of an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 can work as a passive device in the passive mode to interact with an active device 200 working in the active mode. As shown in FIG. 1A, when the user needs to pay, the user can bring the active device 200 (such as a mobile phone, a watch, a bracelet, etc.) with a communication module of the user close to the electronic device 100 provided by an embodiment of the present disclosure set by the merchant. Thus, the electronic device 100 can sense the active device 200 of the user through the communication module and communicate with the active device 200 to transfer payment information. Then, as shown in FIG. 1B, the active device 200 of the user can display a corresponding payment page according to the payment information. When the user completes the payment by performing a payment operation (such as the user clicking a payment control “Confirm Payment” displayed on the payment page) on the active device 200 according to the payment page, the active device 200 of the user can display a payment completion interface, as shown in FIG. 1C, to complete the payment of the user to the merchant.

[0038] For example, the electronic device is taken as an ordering device. FIGS. 2A-2C show application scenario diagrams of another electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 can work as a passive device in a passive mode to interact with an active device 200 working in an active mode. For example, as shown in FIG. 2A, when the user needs to order, the user can bring the active device 200 (such as a mobile phone, a watch, a bracelet, etc.) with a communication module function close to the electronic device 100 provided by an embodiment of the present disclosure arranged on a dining table. Thus, the electronic device 100 can sense the active device 200 of the user through the communication module and communicate with the active device 200 to deliver ordering information. Then, as shown in FIG. 2B, the active device 200 of the user can display a corresponding ordering page according to the ordering information. When the user completes the ordering operation on the active device 200 according to the ordering page (for example, the user selects "meal 1" and "meal 3" in the ordering page and clicks the control "confirm selection" for confirming the order), as shown in FIG. 2C, the active device 200 of the user can display an ordering completion interface, thereby completing the operation of the user to conveniently order.

[0039] Of course, the electronic device can also be used as an active device, which is not described herein. It should be noted that the electronic device described above is only illustrative. Those skilled in the art should understand that other forms of electronic devices that can emit light are also within the protection scope of the present disclosure.

[0040] FIG. 3 shows a front view of an electronic device 100 according to an embodiment of the present disclosure. As shown in FIG. 3, the electronic device 100 includes a housing 120 and a light-emitting assembly 140. The electronic device 100 further includes a communication module (not shown in FIG. 3).

[0041] The housing 120 is a mounting base of the electronic device 100. The light-emitting assembly 140 and other modules (such as the communication module) of the electronic device 100 can be mounted on the housing 120. The mounting on the housing 120 can be direct mounting or indirect mounting. The direct mounting can be directly connected and mounted with the housing 120. The indirect mounting can be connected and mounted with the housing 120 through other connecting structures. The mounting on the housing 120 can be mounted in the housing 120 or mounted outside the housing 120. The mounting in the housing 120 can be that the part mounted with the housing 120 is located in the housing 120, and other parts can be located in the housing 120 or outside the housing 120. The mounting outside the housing 120 can be that the part mounted with the housing 120 is located outside the housing 120, and other parts can be located in the housing 120 or outside the housing 120.

[0042] The shell 120 can be a thin-walled structure. The shell 120 can have a receiving cavity for receiving other modules. The receiving cavity can be an open receiving cavity. In some embodiments, the electronic device 100 can also include a cover plate. The cover plate can be connected with the shell 120 to close the receiving cavity. In some embodiments, the electronic device 100 can also not include a cover plate. In some embodiments, other parts can also serve as the cover plate. The shell 120 can include a bottom plate and a side plate. The side plate is arranged at one side of the bottom plate and is connected with the bottom plate. The bottom plate and the side plate jointly define the receiving cavity. The outer contour of the shell 120 can be of any shape, such as a square, a rectangle, a circle, an ellipse, a triangle, a polygon, or even an irregular shape, etc. The shell 120 can be symmetrical or asymmetrical. The outer contour shape of the shell 120 can be adaptively adjusted according to product design needs. The inner wall of the shell 120 can be provided with mounting structures for connecting with other modules according to mounting needs. The material of the shell 120 can be of any material, such as a metal material, a plastic material, a polymer material, etc. The present disclosure does not make any limitation in this regard. The outer contour shape of the shell 120 of the electronic device 100 shown in FIG. 3 is a circle. It should be understood by those skilled in the art that the outer contour of the shell 120 can also be of other shapes, which are also within the protection scope of the present disclosure.

[0043] The light emitting assembly 140 is configured to emit light. In some embodiments, the electronic device 100 can include a group of light emitting assemblies 140. In some embodiments, the electronic device 100 can include multiple groups of light emitting assemblies 140. The light emitting position (also called the light emitting-out position) of the light emitting assembly 140 can be designed into different shapes and arranged at different positions according to product design, product function and aesthetic needs, which are not limited by the present disclosure. Taking FIG. 3 as an example, the electronic device 100 includes six groups of light emitting assemblies, which are the first light emitting assembly 140(a), the second light emitting assembly 140(b), the third light emitting assembly 140(c), the fourth light emitting assembly 140(d), the fifth light emitting assembly 140(e) and the sixth light emitting assembly 140(f).

[0044] As mentioned before, the electronic device 100 can also include a communication module. The form of the communication module is as mentioned before, which will not be repeated here. As mentioned before, the communication module includes an antenna assembly. In order to ensure the stability of the operation of the antenna assembly, the shell 120 is provided with an antenna clearance area 160. No metal can appear in the antenna clearance area 160. Therefore, the light source in the light emitting assembly 140 cannot appear in the antenna clearance area 160. The position of the exemplary antenna clearance area 160 in the front view is shown by the shaded part in FIG. 3. It should be understood by those skilled in the art that the antenna clearance area 160 can also be at other positions, and the position of the antenna clearance area 160 is adapted to the product structure design.

[0045] In some embodiments, the electronic device 100 can further include other modules (not shown in FIG. 3), such as a key module, a control module, and the like. The present disclosure does not limit other modules of the electronic device 100.

[0046] FIG. 4 shows an exploded view of an electronic device 100 according to an embodiment of the present disclosure. The exploded direction shown in FIG. 4 is the exploded direction of the central axis 121 of the housing 120. As shown in FIG. 4, the light-emitting assembly 140 can be mounted on the housing 120. The light-emitting assembly 140 includes a light source 142 and a light guide 144. In some embodiments, the light-emitting assembly 140 can further include a light-reflecting member 146.

[0047] The light source 142 can be mounted on the housing 120. Specifically, the light source 142 can be mounted inside the housing 120, such as in a receiving cavity. The light source 142 can emit light outward, such as visible light. As mentioned above, the antenna in the communication module includes an antenna clearance area 160. The distance between the light source 142 and the antenna of the communication module is greater than a preset antenna distance threshold, so that the light source 142 is located outside the antenna clearance area 160. The distance between the light source 142 and the antenna of the communication module is the minimum distance between the light source 142 and the antenna. That is, the distance between the position closest to the antenna in the light source 142 and the antenna. The sizes of the antenna clearance areas 160 of different antennas can be different.

[0048] As shown in FIG. 4, the first light source 142(a) can be the light source in the first light-emitting assembly 140(a). The first light source 142(b) can be the light source in the second light-emitting assembly 140(b), the third light-emitting assembly 140(c), the fourth light-emitting assembly 140(d), the fifth light-emitting assembly 140(e), and the sixth light-emitting assembly 140(f).

[0049] The light guide 144 can conduct the light emitted by the light source 142 so that the light exits from a specified plane. The light guide 144 is a transparent or translucent plastic material part. Light can be conducted inside the light guide 144 by reflection, refraction, and the like, and the light can be conducted to a specific position or shape through the light guide 144. The light guide 144 has a high refractive index and a low light absorption performance. The light guide rate of the light guide 144 is higher than a preset light guide rate threshold. The light guide rate threshold can be 90%-98%, or 80%-90%, or higher or lower. The material of the light guide 144 can be plastic material, such as PC (polycarbonate) material, PMMA (polymethyl methacrylate) material, and the like.

[0050] The first light guide 144(a) can be a light guide in the first light emitting assembly 140(a). The second light guide 144(b) can be a light guide in the second light emitting assembly 140(b). The third light guide 144(c) can be a light guide in the third light emitting assembly 140(c). The fourth light guide 144(d) can be a light guide in the fourth light emitting assembly 140(d). The fifth light guide 144(e) can be a light guide in the fifth light emitting assembly 140(e). The sixth light guide 144(f) can be a light guide in the sixth light emitting assembly 140(f).

[0051] The light guide 144 can be mounted on the housing 120. The light guide 144 can include a light-in surface 144-1 and a light-out surface 144-2. The light guide 144 as referred to herein can be any one or more of the first light guide 144(a), the second light guide 144(b), the third light guide 144(c), the fourth light guide 144(d), the fifth light guide 144(e), or the sixth light guide 144(f). The light-in surface 144-1 faces the center of the housing 120, and the light source 142 is opposite to the light-in surface 144-1. The light-out surface 144-2 is not parallel to the light-in surface 144-1, and the light-in surface 144-1 is located at one end of the light-out surface 144-2 close to the center of the housing 120. The light-out surface 144-2 faces the outer surface of the housing 120 and is exposed outside the housing 120.

[0052] The center of the housing 120 can be a central axis 121 of the housing 120. The central axis 121 of the housing 120 is not coplanar with the outer surface of the housing 120. The outer surface of the housing 120 can be a plane or a curved surface. When the outer surface of the housing 120 is a plane, the central axis 121 of the housing 120 can be perpendicular to the outer surface of the housing 120. When the outer surface of the housing 120 is a curved surface, the central axis 121 of the housing 120 can pass through the center of curvature of the outer surface of the housing 120 and point to the radial direction of the outer surface of the housing 120.

[0053] The light-in surface 144-1 is a surface through which light rays enter. The light source 142 is arranged opposite to the light-in surface 144-1, and the light rays emitted by the light source 142 enter the light guide 144 through the light-in surface 144-1. The distance between the light source 142 and the light-in surface 144-1 is within a predetermined range, so that as many light rays as possible from the light source 142 are directed to the light-in surface 144-1, reducing light leakage.

[0054] The light exit surface 144-2 is a surface from which light rays exit. The light exit surface 144-2 is exposed outside the housing 120, so that light rays exiting the light exit surface 144-2 can be exposed outside the housing 120 to achieve a lighting effect. The light exit surface 144-2 can face the outer surface of the housing 120. The light exit surface 144-2 and the light entry surface 144-1 are not parallel. The light entry surface 144-1 and the light exit surface 144-2 face different directions, respectively. In some embodiments, the light exit surface 144-2 and the light entry surface 144-1 can be arranged perpendicularly. In some embodiments, the light exit surface 144-2 and the light entry surface 144-1 can form an angle, such as an acute angle, a right angle, or an obtuse angle. The light entry surface 144-1 is located at the side of the light exit surface 144-2. That is, the light rays of the light source 142 enter the light entry surface 144-1 from the side of the light exit surface 144-2 and then exit the light exit surface 144-2. In some embodiments, the light entry surface 144-1 is located at the end of the light exit surface 144-2 close to the center of the housing 120. That is, the light entry surface 144-1 is located closer to the center of the housing 120 than the light exit surface 144-2. Therefore, the light source 142 can be closer to the center of the housing 120. Regardless of the position and direction of the light exit surface 144-2, the light source 142 can be concentrated towards the center of the housing 120, so that the light source 142 is located in the area of the center of the housing 120, the volume of the light source 142 is reduced, and the concentration of the light source 142 is improved. At the same time, since the light entry surface 144-1 faces the center of the housing 120, regardless of the position and direction of the light exit surface 144-2, the light source 142 only needs to be opposite to the light entry surface 144-1, so that the arrangement of the light source 142 is simpler. That is, regardless of the position and direction of the light exit surface 144-2, the light rays of the light source 142 exit in the same plane or in parallel planes, which greatly reduces the difficulty of arranging the light source 142.

[0055] The light guide 144 can be installed on the housing 120 in various ways. In some embodiments, the light guide 144 can be installed outside the housing 120 and expose the light exit surface 144-2 outside the housing 120, such as the first light guide 144(a). In some embodiments, the housing 120 can be provided with a mounting hole 123. The light guide 144 can be installed inside the housing 120, such as in the accommodation cavity. At this time, the light exit surface 144-2 can pass through the mounting hole 123 and be exposed outside the housing 120. For example, the second light guide 144(b), the third light guide 144(c), the fourth light guide 144(d), the fifth light guide 144(e), or the sixth light guide 144(f). At this time, the profile of the mounting hole 123 matches the profile of the light exit surface 144-2.

[0056] When the light guide 144 is mounted on the housing 120, part of the surface of the housing 120 is opposite to part of the side surface of the light guide 144. The side surface of the light guide 144 can be a surface connected to the light-out surface 144-2 or the light-in surface 144-1. The surface of the housing 120 opposite to the side surface of the light guide 144 can shield the side surface of the light guide 144, thereby reflecting the light emitted from the side surface of the light guide 144 and reducing the leakage of the light.

[0057] In some embodiments, when the number of the light guides 144 is multiple, the light guides 144 in the multiple light guides 144 that are within a preset first threshold are connected by the connecting piece 144-5. It should be noted that the light transmittance of the connecting piece 144-5 is lower than a preset second threshold. The connecting piece 144-5 is made of a material different from that of the light guide 144. The connecting piece 144-5 can reflect the light emitted from the light guide 144 towards the connecting piece 144-5. That is, when the multiple light guides 144 are close to each other, the multiple light guides 144 can be connected by the connecting piece 144-5, thereby improving the integration of the light guides 144, reducing the installation difficulty of the light guides 144, and improving the light shielding between the different light guides 144 to avoid light crosstalk.

[0058] The connecting manner of the connecting piece 144-5 and the connected light guide 144 can include various manners, such as bonding, hot melting, etc.

[0059] In some embodiments, the connecting piece 144-5 and the connected light guide 144 are integrally formed. In some embodiments, the connecting piece 144-5 and the connected light guide 144 are integrally formed by a two-shot injection molding method. The two-shot injection molding refers to a molding process in which two different materials are injected into the same mold, so that the part molded by the two materials. Some of the two materials are different colors, and some are different in hardness, thereby improving the appearance and assembly performance of the product.

[0060] As mentioned above, in some embodiments, the light emitting assembly 140 further comprises a light reflecting member 146. The light reflecting member 146 can be mounted on the housing 120. The light reflecting member 146 is disposed on a side of the light guide member 144 and covers at least part of the surface of the light guide member 144 other than the light entrance surface 144-1 and the light exit surface 144-2. The light reflecting member 146 can be disposed on the side of the light guide member 144 opposite to the light exit surface 144-2. The light reflecting member 146 is configured to reflect the light rays emitted from the light guide member 144 back into the light guide member 144. The light reflecting member 146 has a low light transmittance. When the light rays are emitted from the light guide member 144 and hit the light reflecting member 146, the light rays are reflected by the light reflecting member 146 and re-enter the light guide member 144, thereby reducing the light leakage. It is noted that in some embodiments, multiple light emitting assemblies 140 can share one light reflecting member 146 depending on the position and size of the light reflecting member 146. For example, in the electronic device shown in FIG. 4, the first light reflecting member 146(a) can be the light reflecting member in the first light emitting assembly 140(a). The second light reflecting member 146(b) can be the light reflecting member in the second light emitting assembly 140(b), the third light emitting assembly 140(c), the fourth light emitting assembly 140(d) and the fifth light emitting assembly 140(e). The third light reflecting member 146(c) can be the light reflecting member in the sixth light emitting assembly 140(f).

[0061] In some embodiments, the at least part of the surface covered by the light reflecting member 146 comprises the surface of the light guide member 144 opposite to the light exit surface 144-2. Here, the light reflecting member 146 can be any one or more of the first light reflecting member 146(a), the second light reflecting member 146(b) or the third light reflecting member 146(c). As mentioned above, the light exit surface 144-2 faces the outside of the housing 120. Therefore, the surface of the light guide member 144 opposite to the light exit surface 144-2 faces the inside of the housing 120. The light reflecting member 146 is disposed on the side of the light guide member 144 opposite to the light exit surface 144-2 and is configured to reflect the light rays emitted from the surface opposite to the light exit surface 144-2 back into the light guide member 144.

[0062] In some embodiments, the light reflecting member 146 includes a top wall 146-1 and a side wall 146-2. The top wall 146-1 is arranged opposite to the surface of the light guide 144 opposite to the light exit surface 144-2. The side wall 146-2 is connected to the top wall 146-1 and is arranged on a side of the top wall 146-1 close to the light guide 144 and distributed around the light guide 144. In this case, the top wall 146-1 can reflect the light emitted from the surface of the light guide 144 opposite to the light exit surface 144-2. The side wall 146-2 can reflect the light emitted from the part of the side surface of the light guide 144. The device composed of the light reflecting member 146 and the housing 120 can reflect the light emitted from the surface of the light guide 144 other than the light entry surface 144-1 and the light exit surface 144-2, so as to avoid the light emitted from the surface other than the light exit surface 144-2 and avoid the light leakage.

[0063] The light source 142 can include a light emitting element and a circuit board. The light emitting element can be a light emitting lamp bead, such as an LED lamp bead. The light emitting element is configured to emit light, such as visible light, outwardly. The light emitting element can be mounted on the circuit board and electrically connected to the circuit board. The circuit board can provide the light emitting element with electric energy.

The first light emitting element 142-1(a) can be a single color light source or different color light sources. The plurality of first light emitting elements 142-1(a) are distributed around the central axis 121 of the housing 120. The light emitting direction of each first light emitting element 142-1(a) is a radial direction. The directions of the arrows in the figure are the light emitting directions of part of the first light emitting elements 142-1(a). The arrangement mode, size and position of the first light emitting elements 142-1(a) in the first light source 142(a) shown in FIG. 5 are only illustrative. Those skilled in the art should understand that the arrangement mode and size of the first light emitting elements 142-1(a) can be designed and adjusted according to the light effect, which is not limited in the present disclosure.

[0065] FIG. 6 shows a structural schematic diagram of another light source 142 according to an embodiment of the present disclosure. The light source shown in FIG. 6 can be the second light source 142(b). The second light source 142(b) can include a second light emitting element 142-1(b), a third light emitting element 142-1(c), a fourth light emitting element 142-1(d), a fifth light emitting element 142-1(e), a sixth light emitting element 142-1(f), and a second circuit board 142-2(b). The second light emitting element 142-1(b), the third light emitting element 142-1(c), the fourth light emitting element 142-1(d), the fifth light emitting element 142-1(e), the sixth light emitting element 142-1(f), and the second circuit board 142-2(b) are mounted on the second circuit board 142-2(b) and electrically connected with the second circuit board 142-2(b). The second circuit board 142-2(b) provides electric energy for the second light emitting element 142-1(b), the third light emitting element 142-1(c), the fourth light emitting element 142-1(d), the fifth light emitting element 142-1(e), and the sixth light emitting element 142-1(f).

[0066] As mentioned above, the light-incident surface 144-1 is located at one end of the light-incident surface 144-2 close to the center of the shell 120, which can make the light sources 142 close to the center of the shell 120, thereby reducing the volume of the light sources 142 and improving the integration of the light sources 142. Therefore, when the light sources 142 are close to the center of the shell 120 and the distance is close enough, different light sources 142 can share the same circuit board, as shown in FIG. 6, which can further improve the integration of the light sources 142, reduce the volume of the light sources 142, and reduce the cost and difficulty of processing and installation. At the same time, since the light-incident surface 144-1 faces the center of the shell 120, different light-emitting elements can be arranged in any direction and position facing the center of the shell 120, further increasing the flexibility of the arrangement of the light-emitting elements. Such a design makes the direction of the light-incident surface 144-1 of different light guides 144 different even if the direction of the light-incident surface 144-2 of the light guides 144 is the same, thereby further improving the integration of the light sources 142 and reducing the volume of the light sources 142.

[0067] FIG. 7A shows a first side view of a light guide 144 according to an embodiment of the present disclosure, and FIG. 7B shows a second side view of the light guide 144 according to an embodiment of the present disclosure. FIG. 7B can be a view observed from above of FIG. 7A. The light guide 144 shown in FIGS. 7A and 7B can be the sixth light guide 144(f). As shown in FIGS. 7A and 7B, the light guide 144 includes a light-incident surface 144-1 and a light-incident surface 144-2. The light-incident surface 144-1 is arranged on one side of the light-incident surface 144-2.

[0068] A plurality of light-exit light guide points 144-31 are arranged on the surface 144-3 opposite to the light-incident surface 144-2 of the light guide 144. The light-exit light guide points 144-31 can break the incident angle of the light, thereby making the light diffuse in different angles and making the concentrated light more uniform, thereby improving the uniformity of the light and the light transmission efficiency. One of the plurality of light-exit light guide points 144-31 can be a protrusion or a groove. When the light-exit light guide point 144-21 is a groove, the groove can be a curved groove or a groove formed by the intersection of a plurality of inclined surfaces. The plurality of light-exit light guide points 144-31 can be a plurality of microstructures distributed on the surface 144-3 opposite to the light-incident surface 144-2. The size of the light-exit light guide points 144-31 can reach millimeters, microns or even nanometers. The plurality of light-exit light guide points 144-31 can be uniformly or non-uniformly distributed on the surface 144-3 opposite to the light-incident surface 144-2. The structure and size of the plurality of light-exit light guide points 144-31 can be consistent or inconsistent. The present disclosure does not limit this. The plurality of light-exit light guide points 144-31 can be formed by laser engraving, can be formed by printing, or can be formed when the light guide 144 is injection molded.

[0069] The surface 144-3 of the light guide 144 opposite to the light exit surface 144-2 is inclined relative to the light exit surface 144-2. The distance from the light exit surface 144-2 of the end of the surface 144-3 of the light guide 144 opposite to the light exit surface 144-2 away from the light entrance surface 144-1 is shorter than the distance from the light exit surface 144-2 of the end of the surface 144-3 of the light guide 144 opposite to the light exit surface 144-2 close to the light entrance surface 144-1. That is, the distance from the light exit surface 144-2 of the end of the surface 144-3 of the light guide 144 opposite to the light exit surface 144-2 away from the light entrance surface 144-1 is shorter than the distance from the light exit surface 144-2 of the end of the surface 144-3 of the light guide 144 opposite to the light exit surface 144-2 close to the light entrance surface 144-1. Such a configuration can make the light rays uniformly radiate to the light exit surface 144-2 without being concentrated at the end of the light exit surface 144-2 away from the light entrance surface 144-1. Thus, the light radiated from the light exit surface 144-2 is more uniform, effectively ensuring the equivalent uniformity and consistency of the light exit surface 144-2.

[0070] The light entrance surface 144-1 is provided with a plurality of light entrance light guide points 144-13. The light entrance light guide points 144-13 can break the incident angle of the light rays, thereby making the light rays diffuse at different angles, making the concentrated light rays more uniform, thereby improving the uniformity of the light rays and the light transmission efficiency. The plurality of light entrance light guide points 144-13 can be distributed along the width direction of the light entrance surface 144-1, so that the light rays can uniformly enter the light entrance surface 144-1 along the width direction of the light entrance surface 144-1. The width direction of the light entrance surface 144-1 can be the direction perpendicular to the incident direction of the light rays. One of the plurality of light entrance light guide points 144-13 can be a protrusion or a groove. When the light entrance light guide point 144-13 is a protrusion, the protrusion can be a circular arc protrusion or a protrusion including a plurality of intersecting surfaces (such as a tooth-shaped, conical, cylindrical). The plurality of light entrance light guide points 144-13 can be a plurality of microstructures distributed on the light entrance surface 144-1. The size of the light entrance light guide point 144-13 can reach millimeters, microns or even nanometers. The plurality of light entrance light guide points 144-13 can be uniformly or non-uniformly distributed on the light entrance surface 144-1. The structure and size of the plurality of light entrance light guide points 144-13 can be consistent or inconsistent. The present disclosure does not limit this. The plurality of light entrance light guide points 144-13 can be formed by laser engraving, or can be formed by printing, or can be formed during the injection molding of the light guide 144.

[0071] Figure 8 shows the cross-sectional view A-A of Figure 3. Figure 8 shows the installation view of the light guide 144, the housing 120 and the light source 142. Figure 9 shows a partial enlarged view of part I in Figure 8. As shown in Figure 9, the first light guide 144(a) is installed on the periphery of the housing 120. The light-incident surface 144-1 of the first light guide 144(a) is located at one end of the light- emitting surface 144-2 close to the center of the housing 120. The light-incident surface 144-1 is opposite to the first light-emitting element 142-1(a). The first light-reflecting element 146(a) and the housing 120 jointly shield other surfaces outside the light-incident surface 144-1 and the light-emitting surface 144-2, so as to reflect the light rays emitted from the other surfaces out of the light guide 144 back to the light-emitting surface 144-2, thereby ensuring that the light rays can be emitted from the light-emitting surface 144-2 and avoiding light leakage.

[0072] Figure 10 shows a partial enlarged view of part J in Figure 8. As shown in Figure 10, the sixth light guide 144(f) is installed inside the housing 120. The light-emitting surface 144-2 of the sixth light guide 144(f) is exposed outside the housing 120 through the installation hole 123 of the housing 120. The light-incident surface 144-1 of the sixth light guide 144(f) is located at one end of the light-emitting surface 144-2 close to the center of the housing 120. The light-incident surface 144-1 is opposite to the sixth light-emitting element 142-1(f). The third light-reflecting element 146(c) and the housing 120 jointly shield other surfaces outside the light-incident surface 144-1 and the light-emitting surface 144-2, so as to reflect the light rays emitted from the other surfaces out of the light guide 144 back to the light-emitting surface 144-2, thereby ensuring that the light rays can be emitted from the light-emitting surface 144-2 and avoiding light leakage.

[0073] In summary, in the electronic device 100 provided by the embodiments of the present disclosure, the light-incident surface 144-1 and the light-emitting surface 144-2 of the light guide 144 are arranged as non-parallel surfaces. The light-incident surface 144-1 is arranged at one end of the light-emitting surface 144-2 close to the center of the housing 120 and faces the center of the housing 120. Therefore, the light-incident surface 144-1 is closer to the center of the housing 120 than the light-emitting surface 144-2. The light source 142 is opposite to the light-incident surface 144-1. Therefore, the light source 142 can be closer to the center of the housing 120. No matter where and in which direction the light-emitting surface 144-2 is located, the light source 142 can be concentrated in the direction close to the center of the housing 120, so that the light source 142 is located in the area of the center of the housing 120, the volume of the light source 142 is reduced, and the concentration of the light source 142 is improved. At the same time, since the light-incident surface 144-1 faces the center of the housing 120, no matter where and in which direction the light-emitting surface 144-2 is located, the light source 142 only needs to be opposite to the light-incident surface 144-1, so that the arrangement of the light source 142 is simpler.
